Notes to Consolidated Financial Statements

1. Organization and Basis of Presentation

Organization and Nature of Operations

Magnolia Oil & Gas Corporation (either individually or together with its consolidated subsidiaries, as the context requires, the “Company” or “Magnolia”) is an independent oil and natural gas company engaged in the acquisition, development, exploration, and production of oil, natural gas, and natural gas liquid (“NGL”) reserves. The Company’s oil and natural gas properties are located primarily in the Karnes and Giddings areas in South Texas where the Company primarily targets the Eagle Ford Shale and Austin Chalk formations. Magnolia’s objective is to generate stock market value over the long term through steady organic production growth, high full cycle operating margins, an efficient capital program with short economic paybacks, significant free cash flow after capital expenditures, and effective reinvestment of free cash flow.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, certain disclosures normally included in an Annual Report on Form 10-K have been omitted. The consolidated financial statements and related notes included in this Quarterly Report should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2025 (the “2025 Form 10-K”). Except as disclosed herein, there have been no material changes to the information disclosed in the notes to the consolidated financial statements included in the Company’s 2025 Form 10-K.

In the opinion of management, all normal, recurring adjustments and accruals considered necessary to present fairly, in all material respects, the Company’s interim financial results have been included. Operating results for the periods presented are not necessarily indicative of expected results for the full year.

Certain reclassifications of prior period financial statements have been made to conform to current reporting practices. The consolidated financial statements include the accounts of the Company and its subsidiaries after elimination of intercompany transactions and balances. The Company’s interests in oil and natural gas exploration and production ventures and partnerships are proportionately consolidated. The Company reflects a noncontrolling interest representing the interest owned by the Magnolia LLC Unit Holders through their ownership of Magnolia LLC Units in the consolidated financial statements. The noncontrolling interest is presented as a component of equity. See Note 10—Stockholders’ Equity for further discussion of the noncontrolling interest.

Segment Information

The Company operates inone reportable segment engaged in the acquisition, development, exploration, and production of oil and natural gas properties (“Operating segment”). Magnolia’s operations are conducted predominantly inone geographic area of the United States. The Operating segment sells oil, natural gas, and NGLs which are disaggregated on the Company’s consolidated statements of operations. The profit or loss metric used to evaluate segment performance is net income reported on the Company’s consolidated statements of operations. The measure of segment assets is reported on the Company’s consolidated balance sheets as Total Assets. Significant segment expenses are the same as those in the consolidated statements of operations.

2. Summary of Significant Accounting Policies

As of March 31, 2026, the Company’s significant accounting policies are consistent with those discussed in Note 2—Summary of Significant Accounting Policies of its consolidated financial statements contained in the Company’s 2025 Form 10-K.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03 “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” requiring disclosure of specified information about certain costs and expenses. ASU 2024-03 is effective for annual periods beginning January 1, 2027, with early adoption permitted. The Company is currently evaluating the potential effect that the updated standard will have on its financial statement disclosures.

3. Revenue Recognition

Magnolia’s revenues include the sale of crude oil, natural gas, and NGLs. The Company has concluded that disaggregating revenue by product type appropriately depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors and has reflected this disaggregation of revenue on the Company’s consolidated statements of operations for all periods presented. The Company’s receivables consist mainly of trade receivables from commodity sales and joint interest billings due from owners on properties the Company operates. Receivables from contracts with customers totaled $160.8 million as of March 31, 2026 and $116.5 million as of December 31, 2025. For further detail regarding the Company’s revenue recognition policies, please refer to Note 2—Summary of Significant Accounting Policies of the consolidated financial statements contained in the Company’s 2025 Form 10-K.

2025 Acquisitions

During the three months ended March 31, 2025, the Company completed various bolt-on property acquisitions of certain oil and natural gas assets totaling $24.1 million in cash.

The Company accounted for the 2026 and 2025 acquisitions as asset acquisitions.

5. Fair Value Measurements

Certain of the Company’s assets and liabilities are carried at fair value and measured either on a recurring or nonrecurring basis. The Company’s fair value measurements are based either on actual market data or assumptions that other market participants would use in pricing an asset or liability in an orderly transaction, using the valuation hierarchy prescribed by GAAP under Accounting Standards Codification (“ASC”) 820.

The three levels of the fair value hierarchy under ASC 820 are as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical investments at the measurement date are used.

Level 2 - Pricing inputs are other than quoted prices included within Level 1 that are observable for the investment, either directly or indirectly. Level 2 pricing inputs include quoted prices for similar investments in active markets, quoted prices for identical or similar investments in markets that are not active, inputs other than quoted prices that are observable for the investment, and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 - Pricing inputs are unobservable and include situations where there is little, if any, market activity for the investment. The inputs used in determination of fair value require significant judgment and estimation.

The Company has other financial instruments consisting primarily of receivables, payables, and other current assets and liabilities that approximate fair value due to the nature of the instruments and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in business combinations and asset retirement obligations.

Recurring Fair Value Measurements

Long-Term Debt

The fair value of the Senior Notes at March 31, 2026 and December 31, 2025 was $413.1 million and $412.4 million, respectively. The fair value is based on unadjusted quoted prices in an active market, which is considered a Level 1 input in the fair value hierarchy. The carrying value of the Senior Notes, net of unamortized deferred financing costs, was $393.4 million and $393.3 million as of March 31, 2026 and December 31, 2025, respectively, and is included in “Long-term debt, net” on the Company’s consolidated balance sheets.

Liability-Classified Stock Based Compensation

The fair value of the liability for future cash-settled stock based compensation was $7.4 million and $5.6 million as of March 31, 2026 and December 31, 2025, respectively, and is included in “Other current liabilities” and “Other long-term liabilities” on the Company’s consolidated balance sheets. The fair value of the liability for future cash-settled stock based compensation is estimated using observable market data (the total shareholder return (“TSR”) of the Class A Common Stock relative to the TSR achieved by a specific industry peer group) and Monte Carlo simulation models, which is considered a Level 2 input in the fair value hierarchy.

Nonrecurring Fair Value Measurements

Certain of the Company’s assets and liabilities are measured at fair value on a nonrecurring basis. Specifically, equity-classified stock based compensation is not measured at fair value on an ongoing basis but is subject to fair value calculations in certain circumstances. For further detail, see Note 11—Stock Based Compensation. There were no other material nonrecurring fair value measurements as of March 31, 2026 or December 31, 2025.
